Contactless
As end users, we have come to love contactless payments, which are becoming a bigger part of daily life. So what features let contactless cards make payments without touching the POS terminal? There are two classes: MSD cards and Contactless EMV cards.
Contactless
A contactless transaction is a fast and secure payment made between a credit card and a POS terminal without direct contact, without reading the card's chip or magnetic stripe. Both the card and POS terminal must support contactless transactions.
Payment Systems
The biggest benefit of contactless payment is completing small transactions quickly. You can pay purchases under 350 TL without a PIN, while purchases above 350 TL require your card PIN.
HSM & Security
In the world of payment systems, keys and their uses are important for transferring information from one place to another, storing information, and securing authorization and scripting steps. Key types are divided into six categories based on their purpose.
EMV
EMV standards form the foundation for chip cards to work on terminals worldwide, but each scheme - VSDC (Visa), M/Chip (Mastercard), AEIPS (Amex), J Smart (JCB), D-PAS (Discover), and UICS (UnionPay) - defines its own keys, rules, and card profiles.
Merchant & POS
Cash on delivery means paying for an online order at the moment of delivery, usually in cash, though some e-commerce sites also accept card payment at the door. It boosts sales and builds trust, but carries risks like missing POS terminals and refused deliveries.

PVKI is the abbreviation for PIN Verification Key Index. It is located within the card's Track 1 and Track 2 data and is used in PVV calculation. It can take values from 1 to 6, usually defaulting to 1.

The PCI Security Standards Council (PCI SSC), founded in 2006 by Amex, Discover, JCB, Mastercard and Visa, has shared its data security and testing standard for accepting contactless payments on smartphones and tablets without extra hardware.

Generating a token from the card number is essential to the security of payments made with mobile devices. The level of tokenization used depends on the need and on how critical the token is. Static tokenization: the token is generated once and stored in a database.
